The inimitable Slim Shady has just reached another milestone in his storied career. The Motor City rap god’s 2005 LP, Curtain Call: The Hits, has become Billboard’s longest-charting Hip Hop album in its chart history. Debuting at #1 in 2005, the 7X-platinum greatest hits compilation has spent a staggering 350 weeks on the Billboard 200.

Of course, it’s not Eminem’s only album to perform so well. 2002’s The Eminem Show has spent an impressive 329 weeks on the Billboard 200, while 2010’s Recovery has stuck around for 288 weeks.

While this undoubtedly breaks a Billboard 200 record, Em might have some more tricks up his sleeve. The normally elusive artist recently issued a “Happy Birthday” video to 50 Cent, which found him rapping the lyrics to 50’s “Places To Go” and before that, the bearded version of Em was taking photos with 2 Chainz.

Sooo this jus happened ……#marshalllikestrapmusic ???

But the most eyebrow-raising bit of news came from an interview with The Defiant Onesdirector Allen Hughes who casually mentioned Dr. Dre was “producing, in the 11th hour, a track for Eminem’s latest album.”

Just a couple of guys from Compton and one from Detroit. With a beard. #thedefiantones

Although there are no further details on a mythical Eminem album available at this time, if he is finalizing a record, hopefully more information will surface in the not-so-distant future.

In the meantime, Em is likely focused on his forthcoming battle rap comedy film, Bodied, which he announced earlier this week. Em serves as the film’s producer.
